Abstract

The metal oxide semiconductor field effect transistor (MOSFET) has gate (12) connected in series with gate protectors (28,29). The gate protectors have dividers (13,16) and a switches (17,18) connected in parallel with divider. A controller (19) receives input signal (20) proportional to input voltage of rectifier and outputs signals (21,22) for controlling switches.
